300ZX Water Leak

The 300ZX water leak repair became top priority soon after I bought my Z. The previous owner had kept the vehicle in the garage for most of its life.

When I purchased it and left it outside, the rainwater quickly found its way inside the rear hatch compartment. It turned out that this water leak is quite common on both the 280Z and 300ZX.

Unfortunately I wasted some money on trying to get this leak fixed before I looked into technical service bulletins. I figured since the hatch compartment was wet that the aging hatch seal must be the cause of the hatch water leak.

I purchased a new hatch gasket from the dealership and this cost me around $150. After replacing the hatch seal I anxiously waited for the next rainfall to come and go. To my disappointment after a hard rain the rear hatch compartment was again like a miniature swimming pool.
